Customers Who Viewed This Item Also Viewed
Ideal for laundry rooms, basements, walk-in closets, garages, or anywhere a light switch isn't in a convenient spot, the First Alert Motion-Sensing Light Socket is a hands-free lighting device that turns on when you enter a room and automatically turns off four minutes after movement stops.
Senses Movement in All Directions
Able to operate in broad daylight or pitch-black darkness, this light socket features a 360-degree motion sensor that will detect a person approaching within twelve feet when installed at an eight-foot height. To achieve maximum motion sensitivity, use the handy arrows marked on the unit to determine the strongest response, adjusting the 180-degree points to face a door or other high-traffic area as needed.
Simple Installation for Immediate Use
With the First Alert Motion-Sensing Light Socket, you can get the convenience of automatic lighting without the expensive installation. Just screw the motion-sensing socket directly into an existing light socket, and then fasten the light bulb into the new fixture. The socket works with 25-100 watt bulbs (the product is not suitable for use with enclosed, shaded, or halogen bulbs).
The First Alert Motion-Sensing Light Socket is backed by a three-year limited warranty.

See it in action in video and note the tape.
Another reviewer mentioned that the range is insufficient. I've found that while the units do respond to a 360 degree circle, they do not respond equally in all directions. The unit responds excellently in two opposite directions and poorly in between. The manufacturer must know this because the center terminal is spring loaded and makes electrical contact about a half turn before the sensor screws tight into the socket. Thus, you can unscrew the unit by about a half turn and still have it work. I've taken a few days and slowly unscrewed the sensor from the ceiling socket a few degrees at a time until the most sensitive direction faces my single point of entry. Works much better that way. Doing similarly might help some folks.
November 2012 addition --- Newer units from this manufacturer make finding the sweet spot easier as they now mold in a small bar (or mark) on the sensor which matches the direction of best sensitivity. My old units are not marked and trial and error is used.
This sensor will only work with ceiling mounted bulbs (according to the instructions, only with incandescent bulbs between 25 & 100W, but see below). It will not work with wall-mounted lights, even if it's a bare bulb, unless you manage to set the sensor in a vertical position (as if it were hanging from the ceiling) AND manage to keep the sensor at least 12 inches from the wall. The problem is that once the light is on, the heat reflected from wall will keep the sensor always on and will not turn the light off after you leave the room. Also, according to the instructions, the sensor will not work if it's inside any kind of enclosure, even if it's glass or clear plastic, it will only work with bare bulbs.
The instructions state that the sensor will NOT work with fluorescent bulbs, but I tried it anyway with a 23 W bulb (100 W incandescent equivalent) and it works, except that it takes a while for the bulb to warm up and for the light to reach its maximum intensity; after that it's fine. The delay is an issue of the fluorescent bulb, not the sensor. I noticed that another reviewer tried a fluorescent bulb and it flickered, but I had no problems except the delay time. It is possible that the other reviewer used a 15 W fluorescent bulb (the 23W bulb I used is close to the minimum 25W recommended). Or, maybe it only works with certain brands of fluorescent bulbs, (my bulb didn't have the brand printed on it, but it's a regular compact spiral one).
The sensor does not have a photocell, so it will always turn the light on once it detects movement. Therefore, it is best for places with low light or no windows where, if you are in the room, you will always need the light on, regardless of whether it's day or night.
